Grave cleaner may have caused horrific wildfire

South Korean police have launched a probe into a man suspected of accidentally igniting the country's worst wildfires in history while cleaning his relatives' gravesites, an investigator said yesterday.

More than a dozen fires have been fanned by high winds and dry conditions, killing 30 people and burning more than 48,000 hectares of forest, the worst of its kind recorded in South Korea, according to the interior ministry.

In North Gyeongsang province's Uiseong - the hardest-hit region with 12,800 hectares of its woodland affected - a 56-year-old man was suspected of mistakenly starting a fire while tending to his grandparents's gravesites on March 22, an official from the provincial police said.

"We booked him without detention for investigation on Saturday on suspicions of inadvertently starting the wildfires," the official said.

Investigators will summon him for questioning once the on-site inspection is complete, which could take more than a month, the official said.

The suspect's daughter reportedly told investigators that her father tried to burn tree branches that were hanging over the graves with a cigarette lighter. The flames were "carried by the wind and ended up sparking a wildfire," the daughter was quoted as saying to the authorities.
